UNITE STATES To all whom it may concern: 7

Be it known that I, GEORGE PHILION, of Mishawaka, in the county of St.Joseph and State of Indiana, have invented new and useful Improvementsin separable Pulleys; and I do hereby declare that the following is afull 1 and accurate. description of the same, referi in a section of therim suflicently wide to admit the shaft is made removable on one side incontradistinction to split pulleys, wherein there is a separation in twosubstantially equal parts.

The object ofmy invention is to make the removable section interlockingwith the rim or body of the pulley, so that it cannot move in a radialdirection out of its position of'engagernent with the adjoining parts ofthe rim, whereby the removable part may be secured in place without theuse of bolts or screws.

The object also is to produce compression on the shaft to fasten thepulley thereon by the act of fastening the removable section in place.

My pulley A may be made-by fastening together suitable pieces of boardwith glue or otherwise,.with the grain alternately in differentdirections to avoid liability to split. I then make two perforations 1)parallel with the axis and about midway from the periphery to the centerbore for the shaft, and then. .with a saWI cut from the periphery intosaid holes and again from said holes into the center inradialdirections, or thereabout, being careful to make the two outs g hon each sidez'. e., from the periphery into one hole and from the samehole to the center-in parallel planes. This removes from one side of thepulley-blank a section 0 having the form of two wedges, one connected atits point to the base of the other, the width of said sec- PATENTOFF1cE.

to the diameter of the shaft which is to be employed, so that the samemay enter through the gap made by the removal of the section 0. Thesection 0, being in wedge form, will fit and make contact on its severedsides when moved toward the center of the pulley until its sides havepassed over the width of the saw kerf, and the overlapping shouldersformed at the perforations 1) form seats for keys d, which when in placewill retain said section in place. Said keys may be tapering, so as toconstitute wedges, and thereby the section 0 may be forced upon theshaft with suflicient pressure to clamp and fasten the pulley thereon.

In Fig. 2 is shown a modification of the structure above described,wherein the separating cuts are not radial nor in parallel planes,

but are so related that they constitute interlocking portions whereonwedges may act to key the parts in place and force the gap-sectionagainst the shaft or bushing to secure and fasten the pulley to theshaft.

Having described my invention, What I claim is 1. The pulley A, having aremovable wedgeshaped gap-section c on one side, provided withinterlocking shoulders and keys d, whereby said section may be securelyretained in place.

2. A pulley A, having cut from one side a keys to force said pulley andsection togetherand clamp the same upon the shaft, substantially as setforth.
